10 
years, including Smerinthus ocellatus, populi, tiliae, Sphinx convolvuli r 
liyustri, livornica (one), Choerocampa elpenor and Macroylossa stella tar iwk 
The 6’. tiliae showed good variation and included vars. obsoleta, Clark, 
and bipuncta, Clark. 
Oporabias and hybrids. — Dr. E. A. Cockayne Oporabia christyi, 
hybrid 0 . christyi $ x 0 . christyi 2 . 0 . dilutata light and dark forms 
from Scotland and Epping Forest. One hybrid $ 0. dilutata $ x 
0 . autumnaria 2 , and preserved larvae of this hybrid. 0 . autumnaria, 
light and dark forms from Scotland. Hybrids 0. autumnaria , 
and O. filiyrammaria 2 , and 0 . filiyrammaria $ , and 0 . autumnaria 2 . 
0. ftliyrammaria from Yorkshire and Scotland. Dr. Cockayne stated 
the hybrid dilutata $ x autumnaria 2 shows the grey-colour of dilutata 
with the markings of autumnaria, i.e., a sharp angle in the elbowed 
line, and a distinct central spot some distance from the line. Probably 
all four are “good” species though they form two groups, dilutata and 
christyi, and autumnaria and filiyrammaria, which, according to Allen, 
hybridise freely inter se. Hybridising is very difficult between the 
two groups. All are found on one hillside at Rannoch, and the larvae 
of filiyrammaria are very different from autumnaria — smaller, darker 
and with distinct longitudinal lines —autumnaria is almost alway a 
uniform pale green. The larvae and imagines are found at different 
dates, and the larvae have a different foodplant. Allen finds all 
together in Ireland and notes the same differences there. 
Disappearance of Charceas graminis. —Mr. A. W. Mera used to 
find this species very common at Wanstead fifteen years ago, but had 
not seen any there during recent years. 
Calamia lutosa at North London.— Mr. G. Brooks reported the 
capture of a specimen at Finsbury Park in the Autumn of 1911. 
February 20th, 1912. — Nyssia zonaria bred. — Mr. J. Riches, two 
male specimens bred from Lancashire pupie that day. 
Lyonetia frigidarierra, H.S.—Dr. T. A. Chapman specimens 
bred from larvae found mining in Sallow in July, at Portresina. The 
exhibitor pointed out that it is much larger than our common 
clerchella (18mm. expanse) and instead of a dark and pale variation 
like clerchella, has a number of forms according to the distinctness of 
markings as well as in general darkness or lightness. A very pretty 
form nearly white with dark transverse markings rather suggests an 
Aryyresthia. 
Hydriecias from the Tutt correction.— Dr. E. A. Cockayne, the 
Hydroecias in which he had found paludis, lucens and crinanensis mixed 
together. Mr. Burrows had identified the specimens exhibited by an 
examination of the anal appendages. H. nictitans from England and 
Scotland, H. crinanensis from Northumberland, Scotland and Ireland, 
H. lucens from Lancashire, also H. lucens from Ireland resembling 
H. paludis. 
Nemeobius rtjcina. — Mr. Y. E. Shaw, pupa reared from ova 
collected at Clandon on the occasion of the Society’s Field-Meeting. 
Euchroe cardamines, variation in corour of chrysarides. — Mr. Y. 
E. Shaw, two chrysalides from larvie taken at Chalfont. These were 
both on the same stem, the upper one being of the more usual putty 
xxii.-xxiii.
